BALING-PRESS.

SPECIFICATION forming part of Letters Patent N0. 762,133, dated June 7, 1904.

Application filed January 22, 1904. Serial No. 190,151. (No model.)

T a/ZZ whom it may con/cern.-

Be it known that I, WALTER BULLARD, a

- citizen of the United States, residing at Chico,

in the county of Butte and State of California, have invented new and useful Improvements in Ealing-Presses, of which the following is a specification.

My invention relates to improvements in baling-presses.

It consistsl in an arrangement of a horizontally-disposed baling-chamber, a second chamber substantially in line therewith and having a vertically-movable bottom and operating connections, 'a feed-hopper located above said second chamber having an intermediate revoluble bottom adapted to receive the material to be baled in charges, and'means by which it may loe periodically inverted to discharge the load into the chamber below, means for operating and locking the said revoluble bottom, a horizontally-reciprocating follower adapted to compress the material into the baling-chamber, and means for putting on the binding-ties by which the bales are held in their compressed condition.

It also comprises details of construction, which will be more fully explained by reference to the accompanying drawings, in

Whicl l Figure 1 is a central longitudinal section of my apparatus. Fig. 2 is a plan of same, partly in section. Fig. 3 is a side elevation having some parts removed. Fig. 4 is a rear view of levers that actuate the bottom of the. chamber. Fig. 5 is a view of the hooks to carry tie-wires.

As shown in the drawings,. A is a frame which may be stationary; but I have in the present case shown it mounted upon wheeled axles, so that it is easily transported from place to place.

B is the baling-chamber, which is located at one end of the frame A and which for the purposes of this description I will call the rear end, as being in the direction of the discharge.

In front of the baling-chamber is a feedchamber 4, having a bottom 5, which is here shown as carried upon lever-arms 6, these arms being pivoted ory fulcrumed near the front of the machine, as shown at 7, and this bottom is capable of being raised or depressed at the proper intervals, as will be hereinafter described. Y

2 is a feed-hopper or source of supply whichis located above the feed-chamber, and this may be supplied with material to be baled either by mechanically-operated .forks or feeders, or it may be supplied by hand from a table located upon the machine in front of the hopper and adapted to receive the materialwhich is to loe baled.

8 is a revoluble or reversible bottom for the hopper 2, and this bottom has centrallydisposed pivots 9 projecting and adapted to travel in openings 10 in the sides of the hopper. The transverse front and rear edges of this bottom 8 have grooves or channels made in them, as at 11, and these grooves or channels are adapted to be engaged by horns 12,-\vhich project from the front edgeof the follower.

Across the lower front part of the hopper is a bridge-board 13, its ends extending into slots at each side, in which it can move forward and back a short distance. When the bottom of the hopper is in a horizontal position, its upper forward edge touches the back edge of the bridge-board, and when the forward end of the bottom is raised the bridgeboard, being actuated by a spring, slides under it far enough -to prevent it from again falling to the horizontal position. The follower is retracted by means of lever-arms 15, the inner ends of which are connected with outwardly-extending plates 16, fixed to the follower and adapted to travel in horizontal slots 17 in the sides of the frame A.

' 18 represents arms having their outer ends pivoted approximately atthe center of the levers 15 and their inner ends turnable upon stationary pivots, as at 19.

2O represents other lever-arms, extending from the fulcrum-point of the arms 18 and forming bell-crank levers, to the outer ends of which yare attached cords, as at 21. These cordslead over guide-rollers, as at 22, near the front of the machine, and the outer ends of the levers 2O 18 being connected by rods, as at 23, it will be seen that a pull upon the cords TOO .end of a rod 2e 21 will act, through the levers 2O 18, to draw them toward the front, and these acting upon the levers 15 will draw the follower out of the baling-chamber.

The operation of the device will be as follows: The bottom or door 8 lies substantially Hat, and the rear end is held down by a springpressed hinged Hap 24, the upper edge of which is hinged at the rear portion of the lower part of the hopper, as shown. The front end is held in place by a hook or hooks on the shaft 25, which extend across the machine contiguous to this end of the door or bottom.v Secured to this shaft are also one or more studs or horns, which project obliquely backward, while the hooks project upward and backward, the horns being beneath the front end of the bottom 8, while the hooks engage catches in the front end of the bottom. One or both ends of this shaft 25 project through the side of the machine and is provided with a crank 251L on the outside, which projects downward and engages the front This rod extending along through suitable guides by the side of the feed-chamber bends down past the slot 17 in the path of the plates 16, which extend out from the ends of the follower. Material to be baled may then be filled in upon the top of this door or bottom. Pulling on the chain or rope 26 moves the follower backward below this feed door or bottom. The chain 26 passes between guide-rollers 26, and the ends of the chain diverge and connect with the ends of the levers 15. Thelevers 18 serve as fulcrums about which levers 15 are moved. When the follower is near the extreme end of its backward stroke, the plates 16 come in contact with the bentend of the rod 25D, and thus pull on the crank 25a, which causes the shaft 25 to turn on its bearings. This disengagesthe hooks from the catches i`n the front end of the door or bottom and causes the horns or studs Ito press up against the door or bottom and raise its front end high enough so that the bridge-board 13 will slide under it. As the front end of the bottom is raised it turns upon its pivoted center, so that the back end is depressed and rests on the follower, with its grooved end in the path of the horns 12. When the follower starts on its return or forward stroke,it releases the rod 25, thus allowing the shaft 25 (which is actuated by a spring) to resume its former position. When the horns of the follower 12 come in contact with the grooves 11 in the bottom 8, the bottom slides forward with the follower, its front corners resting upon suitable tracks 30 near the ends of the bridge-board 13. Straps or chains 29 have one end fixed to the hopper and the other to the pivot-pins, which project from the bottom 8 through the sides of the hopper, and when these become taut they lift the front end of the bottom fromthe bridge-board, and as the follower brings the back end of the bottom forward it is brought to an upright position, standing on the follower and forming the front side of the hopper, thus dumping the charge from the bottom 8 into the feed-chamber below.

The guide straps or chains 29 may be made short enough so that they will draw the bottom past a perpendicular position, so that it will drop over automatically or its top may be pushed over by hand, and it will then fall to its former position, the spring-pressed flap 24 yielding to let it pass and' the hooks on the shaft 25 engaging the opposite end,whieh has now become the front end.

In order to prevent an escape of the material through the openings in which the pivotpins of the bottom 8 work, I have shown plates 32 pivoted at the upper angle and having the lower edge curved to correspond with the curve of the opening 10, so as to form comparatively narrow channels that will not permit the escape of material while it is being placed in the hopper, and when the bottom 8 is moved so as to turn and reverse,as described, its central pins being held or guided by the flexible connections 29 will follow the curvature of the channel formed between the edge of the plate 32 andthe edge 10 of the opening in the side of the hopper.

When the material has been discharged into the lower chamber, as previously described, the plates 32 will be pushed out of the way by the pins as the door 8 falls down to its original position and allow the pivot-pins to move through the curvature of the upper side of the opening 10, and thus return to a point of rest in the bottom of the notch or groove 10.

The bottom 5 of the chamber 4 is actuated by `levers 33 34, connected together, as plainly thown in the drawings, and acting similarly to a toggle-lever. By this construction of ehe levers I am able to apply a positive and squal lifting power to both sides of the movable bottom, and thus insure the accurate action of the bottom and its latches.

A rod 36 connects with the end of the lever 34, and by pulling upon this rod the levers act to raise the bottom 5 to the level of the bottom ofthe baling-ehamber, where it is engaged by the hooks or latches, which hold it in its raised position. This raising of the bottom 5 presses the loose charge lying between this bottom and the bottom 8 and prepares it for the action of theh'follower, which being moved forward forces the charge into the baling-chamber, and as the follower moves back its plate 16 contacts with the arms 40 of a rock-shaft 41, upon which the latches are carried, and disengages these latches and allows the bottom 5 to again drop into position to receive the next charge from the hopper.

The baling-chamber has a door or back, as at 37, which is carried by hinges 38 at the top, and at the bottom has latches by which it is normally held in a closed position. These TOO ILO

latches are disengaged by movement of a lever, as at 38, to allow this back portion to be opened when a bale is completedand ready to be discharged.

A sliding yoke 39 is movable vertically in guides upon the outer sides of the press, and this yoke extends across the bottom ofthe baling-chamber and has hook-rods 42 attached to it and lprojecting up through the open spaces between the bars which form the baling-chamber. These hook-rods are raised by pulling upward upon the yoke until the hooks are above the top of the baling-chamber, and the tie-wires are attached and pulled down by the downward movement of the yoke and the hooks. As the follower is reciprocated and successive charges of material are forced into the baling-chamber the material pushes the wires back until the bale is completed, when the Wires will encircle the bale from the top over the back and below the bottom and then by means of the hooks the free ends may be pulled up through the channels in the follower in the front of the bale, thus bringing the wires into position for the final tie and securing of the bale in its compressed condition before the rear door has been opened.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, isM
